A Dytran 5803A load cell having sensitivity of 0.231 mV/N is embedded in the hammer head to measure the force imparted into the deck. What I think your meter is picking up is the massive deceleration of the hammer upon contact with the object spiking massively the x/y/z axis to something rediculous like 20-30m/s. The two common non-destructive force excitation. The characterisation of vibration in buildings often involves exciting the building structure with a force and measuring the vibration response. The input force frequency range can be controlled by changing the hammer tip in two ways: Hammer Mass - Decreasing the mass of the hammer tip causes the hammer to contact the structure for a shorter amount of time. INTRODUCTION Construction noise and vibration issues must be considered an essential part of the assessment of the development of any transportation facility. The IH series IEPE impact hammer range features a rugged force sensor that is integrated into the hammers striking surface.The force sensor serves to provide a measurement of the . where impact vibration in conjunction with an applied push or pull force will assist in the recovery of a stuck fish from within the wellbore.
